Embodiment 1

[0021] Embodiment one, such as Figure 1 to Figure 2 As shown, including the near-field probe, the near-field probe is fixedly installed on the four-axis robot arm, the four-axis robot arm is fixedly installed on the base, the workpiece to be measured is fixedly installed on the base through the positioning fixture, and the near-field probe is electrically connected to the On the device, the control device is electrically connected to the four-axis mechanical arm and the spectrum analyzer respectively;

[0022] The control device includes a motion control module, an electromagnetic detection control module and a data processing module. The motion control module is used to control the movement of the four-axis mechanical arm, the electromagnetic detection control module is used to control the opening and closing of the near-field probe, and the data processing module is used to control the spectrum analysis. Instrument data processing.

[0023] Working principle: The use of ne...

Embodiment 2

[0025] Embodiment 2. In this embodiment, as a preferred technical solution of Embodiment 1, the near-field probe is electrically connected to the display device and the alarm device. The working condition of the near-field probe is displayed through the display device, which is convenient for remote observation. Once the drive shaft where the near-field probe is located touches the limit position, it will stop immediately, and the alarm device will prompt the operator to reposition the workpiece to be detected.

Embodiment 3

[0026] Embodiment 3. This embodiment is a preferred technical solution of Embodiment 1. The data processing module is used to store the data of the workpiece under test, and process and generate an analysis report. In actual use, different styles of near-field probe ends can be used according to the different near-field measurement environments. The control device sends out signals to control the spectrum analyzer for data processing. The spectrum analyzer has the function of quickly generating detection analysis reports and report storage functions. , query history report function, print document function, export document function and other functions. For example, when the experiment needs to analyze the experiment report data vertically, the analysis data points can be quickly captured through the query and export functions of the historical analysis report, thereby speeding up the analysis speed and improving work efficiency.
